What are the characteristics of plastic synthetic paper labels?

The main component of synthetic paper is polypropylene plastic, which can be reused and completely combusted, which will not affect the service life of the incinerator, and will not produce toxic gases, so as to avoid secondary pollution and meet the requirements of modern environmental protection. Therefore, synthetic paper labels are also environmentally friendly labels. It is suitable for making high-quality labels, such as cosmetics, personal hygiene products and other daily chemical products and ** labels, and is also suitable for situations that require certain durability and moisture-proof, such as gasoline barrel labels, household product labels, etc.

It is an ideal labeling material for polypropylene containers and environmental protection. Some synthetic papers are particularly suitable for wet wipe labels; Some specially coated synthetic papers have a surface that can be printed with heat transfer. Overall, it has a wide range of applications and great prospects.

Environmental protection, PP synthetic paper raw materials** and manufacturing process will not cause environmental changes and damage, PP synthetic paper can be 100% ** after use, even if incineration, because its plastic substrate only contains carbon and oxygen, will not produce toxic gases. Plastic instead of paper, plastic instead of wood, synthetic paper raw materials do not need wood and natural plant fibers, can save a lot of forest resources and reduce environmental pollution. Economy.

Calcium carbonate {CAC03) mineral filling, weight ratio up to 60%, can effectively reduce the consumption of plastics, and calcium carbonate is cheap and stable. It has good processability, and can be used for cutting, die-cutting, embossing, hot stamping, drilling, sewing, folding, gluing and other processing methods. Very durable, strong, puncture-resistant, tear-resistant (especially transverse), abrasion-resistant, foldable and foldable.

Synthetic paper has the following characteristics:

High intensity. These include tensile strength, tear strength, and impact strength.

By applying the appropriate surface treatment to the surface of synthetic paper, synthetic paper can even produce better printing results than ordinary paper.

Outstanding resistance to water, oil and chemicals.

The size is stable and not easy to age.

However, synthetic paper also has inherent drawbacks due to its material composition that is different from that of traditional paper:

Poor heat resistance. It is not resistant to folding, and folding will produce crease lines that are difficult to disappear.

Application of PP synthetic paper Because PP synthetic paper has the characteristics of both plastic and paper, it has a wide range of applications in many aspects, mainly in the following three aspects: high-quality printing. Such as posters, pictorials, **, maps, almanacs, books, etc.

Scope of application: PP synthetic paper has the characteristics of both plastic and paper, so it has a wide range of applications in many aspects, mainly in the following three aspects: high-quality printing:

AS (san) acrylonitrile - styrene transparent strong gel AS is a copolymer of acrylonitrile (A) and styrene (S), with medium weather resistance, not affected by high humidity environment, resistance, general grease, detergent and mild alcohol, poor fatigue resistance, not easy to crack due to energy stress, high material transparency, and better fluidity than ABS.

Suitable plastic products: trays, cups, tableware, toothbrushes, refrigerator compartments, knobs, lighting accessories, ornaments, instrument mirrors, packaging boxes, stationery. ABS acrylonitrile-butadiene-styrene copolymer ABS acrylonitrile (chemical corrosion resistance, surface hardness) butadiene (tough) styrene (good processability, good dyeing ability, poor weather resistance, easy oxidation) has good comprehensive properties, high impact toughness and good mechanical properties, excellent heat and oil resistance and chemical stability, dimensional stability, easy machining, surface plating, good electrical properties.

Suitable plastic products: for general structure or wear-resistant force transmission parts and corrosion-resistant equipment.

Suitable plastic products: all kinds of gears, turbines, racks, cams, bearings, mandrels, pulleys, conveyor chains, nuts, washers, pump impellers, lampshades, containers, shells, covers, high temperature electrical products, hair dryer shells, fire cow shells, motor shells, tool boxes, baby bottles, camera parts, hard hats, food plates, medical equipment, CDs, etc. Other:

Shrinkage Appropriate thickness. The overflow value can be added to the glass fiber to improve its shrinkage, mechanical strength, temperature resistance, and the rigidity will increase after long-term use at about 100 degrees, and the product can be annealed to improve the internal stress. The mechanical properties of PA nylon PA such as tensile and compressive strength change with temperature and moisture absorption, so water is relatively a plasticizer of PA, after adding glass fiber, its tensile and compressive strength can be increased by about 2 times, and the temperature resistance is also improved accordingly, the wear resistance of PA itself is very high, so it can be operated without lubrication, if you want to get a special lubrication effect, you can add sulfide to PA.

The types of synthetic paper, according to the different production raw materials, are divided into PP synthetic paper, HDPE synthetic paper, PS synthetic paper, PVC synthetic paper, PET synthetic paper, ABS synthetic paper, etc.; According to the different fillers, it can be divided into filling CAC03 (calciumcarbonate) type, clay (clay, the main components SiO2, Al2O3) type, SiO2 (Silica) type, mica (talc) type, TiO2 (titanium dioxide) type and composite (more than two filling) types; According to the different production methods, it is divided into calendering method (such as soft PVC), casting method (such as CPP), blown film method (such as HDPE), bidirectional stretching method (such as BOPP, BOPET), etc.; According to the different structures, it is divided into single-layer synthetic paper, three-layer synthetic paper, five-layer synthetic paper, etc.

The characteristics of synthetic paper in-mold labels: PP is made of raw material and bidirectional stretching with inorganic filler, which has the characteristics of paper and plastic film; Compared with general paper, it has better acid and alkali resistance, waterproof, oilproof, mildew-proof, and friction resistance. It is completely attached to the container, and even the edges of the paper with special shapes are not protruding or easy to fall off.

No coating processing, there is no problem of coating peeling, the rubber layer behind is easy to exhaust streaks, the molding time is short, and the efficiency is high. Excellent weather resistance, no discoloration or cracking will occur in harsh outdoor environments such as ultraviolet rays, and can be used or stored for a long time. The smoothness, flatness and thickness of the surface height have excellent compatibility with the adhesive.

The surface is smooth and white, which can faithfully reflect the printing effect. It is suitable for rotary offset printing and flexo printing. There are different grades of self-adhesive products, which can be used as long-lasting adhesives and removable adhesives.

For offset printing, small and medium-sized batches of label products, gravure printing is recommended if large-scale printing; If you have high requirements for ink, UV printing is recommended. ‍‍

The in-mold label and the bottle body are completely integrated, and the in-mold label material is usually made of the same material as the plastic bottle body, and the plastic bottle can be crushed together after the product is used, and the reuse rate is higher and the cost is low, so some people classify the in-mold label as a green packaging material, and the plastic bottle with a self-adhesive label is more troublesome, and the self-adhesive label must be removed first, and then the self-adhesive label is removed, and then the use is relatively high, compared to the low efficiency and high cost. Therefore, it can be said that in-mold labels are in line with the development trend of green packaging. The in-mold label and container molding are completed at one time, which reduces labor costs, eliminates post-processing, delivers goods immediately, reduces inventory, shortens the production cycle, and improves production efficiency.

In addition, it has good printing performance, and can be printed with exquisite patterns in the same way as non-monoplastic labels. ‍‍

The appearance is novel and beautiful, the in-mold label and the plastic container are formed together, the in-mold label and the bottle body are naturally touched, the inlay is firm, the label changes with the shape of the powder bottle, and the corners of the label can not be seen on the plastic bottle, and the outside is very beautiful. The label is deformed with the deformation of the powder bottle, so there will be no blistering and wrinkling. Feel smooth, especially for the label as the main outer packaging of daily chemical products, the advantages are self-evident, the printing effect of the label is good, the details of the palace and the delicate design pattern of the picture can be printed, with a strong visual expression, the label in the mold is closely combined with the bottle body, the label and the container are well drilled, the label in the mold has no corners, the label will not be separated from it when the container is warped and squeezed, and there will be no warping and label dropping like the self-adhesive.

Resistant to twisting, scratching and contamination during production and shipping, labels remain intact and aesthetically pleasing for a long time. In a humid environment, the in-mold label will not protrude or become moldy.

Strong anti-counterfeiting function, the system of in-mold labeling is relatively complex, requires special processing molds (in-mold labeling manipulators) or modifications to the original molds, a set of molds is hundreds of thousands of yuan, and the production cost is higher, which greatly reduces the possibility of counterfeiting, so as to provide users and manufacturers with more reliable means of brand protection. At present, there are only a few companies in China that can provide in-mold label labeling services. There are many variations in the mold design, label printing and processing, and labeling and forming processes, so there are technical barriers to in-mold labels, and it is difficult to forge and imitate.

In contrast, self-adhesive labels are now very popular, and the technology is mature and counterfeiting is not only easy, but also very low-cost, so the counterfeit and shoddy products of self-adhesive labels are rampant and damage the interests of manufacturers. ‍‍

Synthetic paper is made of chemical raw materials such as olefins and then added with some additives, which has soft texture, strong tensile strength, high water resistance, light resistance, cold and heat resistance, and can resist the corrosion of chemical substances without environmental pollution, good air permeability, and is widely used in the printing of high-end artworks, maps, albums, high-end books and periodicals. Synthetic polymer materials (such as polyethylene, polypropylene, etc.) are used to pull film (laminated or blown film) to make paper semi-finished products, and then use chemical or physical methods to make them paper, such as sanding can increase opacity, and treating the surface with chemicals can obtain liquid-repellent properties. Another type of synthetic paper products can use synthetic pulp, which is copied after pulping treatment.

Synthetic paper has extremely high tensile strength, extremely high tear strength, good insulating properties, optical properties and excellent wet strength. It is used as insulating material, sea drawing, military ground drawing, etc.

It is also called chemical film paper, polymer paper, plastic paper, etc. Its main raw materials are organic resins such as polyethylene, polypropylene, and polystyrene. The manufacturing method is that firstly, the above-mentioned resin is melted, extruded, and film-formed, and stretched along different axial directions to form a thin film; Then, put the film on"Paper-like"It is processed to make it opaque and white, and then it is made into synthetic paper.

This kind of paper has high tensile strength, and is not afraid of water, not moth-eaten, elastic, can be heat-insulated, dimensionally stable, smooth surface, suitable for books and printing. It is mostly used to make fishery paper, nautical charts, hollow cards, water-resistant newspapers, record bags, commodity labels, outdoor advertising, business cards, etc. Its disadvantage is that it has poor folding resistance, and there are creases that are not easy to disappear after folding.

Waste synthetic paper** has difficulties.

Synthetic paper is a multifunctional material that is processed by extrusion process with resins such as polyolefins and inorganic fillers as the main raw materials, and has the characteristics of plastic and paper. Synthetic paper is a new plastic material product, but also an environmentally friendly product, with light specific gravity, high strength, tear resistance, good printability, shading, ultraviolet resistance, durable, economic and environmental protection. Since the production process of synthetic paper is pollution-free, it can be 100% ** and recycled, which is a major reform of modern paper production.

Synthetic paper has a history of more than 30 years in foreign countries, especially in developed countries such as the United States, Japan, and Canada. With the strengthening of global environmental awareness, ordinary fiber paper has caused a lot of pollution, accelerated the development of synthetic paper, and the continuous emergence of new synthetic paper varieties has expanded the application range of synthetic paper.
